3.3.2.5 Calculating the expected service life for an existing application
The following procedure can be used to better verify whether a CFast card with SLC or MLC technology should
be used in a particular application.
•
Read the "Average erase count" of the data storage device via S.M.A.R.T.
•
Fully operate the system with the respective data storage device over a defined period of time (e.g. 1 week).
•
Determine the number of completed erase cycles with "Average erase count".
•
Calculate the expected service life using the maximum guaranteed write/erase cycles (MLC: 3000, SLC:
100,000).
Example for an MLC CFast card over the period of a week:
